DISK HARROW- Specification of Letters Patent.

Patented June 12, 1906.

To all whom it may concern..-

Be it known that I, LEWIS E. WATERMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Disk Harrows, of which the following is a specification.

The object of this invention is to hold the inner ends of the two disk gangs down to their work in an adjustable manner.

In the accompanying drawings, Figure 1 is aperspective view of my improved harrow. Figs. 2 and 3 show the construction of the connections of the bars 3 with the disk gangs.

7 The harrow represented in the drawings in the main is of an old construction, my improvements relating to the means for holding the inner ends of the disk gangs down to the Work.

To the tongue 1 is secured a frame composed of the cross-bar 2 and diagonally-extending brace-bars 3, having their rear free ends connected to the disk gangs 4 and 5 by the construction shown at Figs. 2 and 3.

The toothed quadrants 6 and 7 are secured to the sides of the tongue, and two levers 8 and 9 one for each quadrant-are provided with the usual dog and thumb-lever engagement with the quadrants.

T0 the lower end of the hand-lever 6 is pivotally connected an adjusting-bar 10, which has its outer end connected to the disk gang 5.

The hand-lever 9 has an adjusting-bar 11 pivotally connected to its lower end, and the outer end of this adjusting-bar has a connection with the disk-gang 4. These two handlevers are shown connected at their upper end in order that both may be moved by the movement of one of them.

To the rear end of the tongue 1 is secured a seat-support 12, which extends upwardly in a straight line for some distance and thence longitudinally. The horizontal portion 13 receives the seat 14.

To the upper end of the strai ht portion of the seat-support is fixedly attac lied a bracket 15, towhich one end of a brace-rod 16 is connected, and the other-end of this brace-rod is secured to the tongue, which acts to support the seat.

A foot-rest 17 is secured to the bracerod 16.

Around the straight portion 18 of the seatsupport is located a sleeve 19, which is fitted to slide thereon and from which extends a hook 20. To the hook 20 is pivotally connected a cross-bar 21 about midway of its length, and its ends 22 and 23 are in eye form.

A link 24 has its upper end inserted in the eye 22 of the cross-bar 21, and its lower end has a pivotal connection with the adjustingbar 10.

A link 25 has its upper end inserted in the eye 23 in the cross-bar 21, and its lower end has a pivotal connection with the adjustingbar 1 1.

The upper end of the sleeve 19 has an outwardly-extending projection 26.

The bracket 15 has a screw threaded socket 27, within which is located a screw 28, having its upper end 29 in crooked handle form.

The lower end of the screw 28 rests on the projection 26 of the sleeve.

By means of the screw 28 the sleeve 19 can be forced downward, which will force the adjusting-bars 10 and 11 downward, and they in turn will force the inner ends of the disk gangs down. This adjustment is utilized to accommodate the height of the pitch of the tongue to the team. If a high hitch is used and the gangs are set angling with relation to one another, the weight of the gangs will rest more heavily on their inner ends, and by allowing the sleeve 19 to slide up the gangs will be leveled.

Should a low hitch be used, the inner ends of the gangs will stand free of the ground, and by forcing the sleeve 19 down the gangs will be leveled.

One end of one 01 the brace-bars 3 is shown at Figs. 2 and 3 and is provided with a notch 30 in its under face, also with a hole 31, through which a bolt 32 passes.

A slide 33 has its top and bottom edges embracing the top and bottom edges of the brace-bar 3. A slot 34 is formed through the slide and receives the bolt 32. A nut 35 clamps the slide to the brace-bar.

The lower edge of the slide 33 is formed with a slot 36, having a portion cut away.

The axle of a disk gang supports a bracket, shown in dotted line, Fig. 2, and this bracket supports a bolt 37, which extends parallel With the axle of the disk gang.

The slide 33 is moved so that the bolt 37 is received in the notch 30 in the brace-bar 3.

The slide 33 is then moved so that the bolt 37 is received within the closed end of the slot 36, when the slide is clamped to the bracebar 3, as shown at Fig. 2. This construction permits of a ready connection between the main frame and disk gangs.

I claim as my invention 1. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a vertically-arranged support, a sleeve slidably connected to the support, a connection between the sleeve and each disk gang, and means for holding the sleeve against movement in one direction.

2. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a vertirally-arranged support, a sleeve slidably connected to the support, a connection between the sleeve and each disk gang, and means for holding the sleeve against movement in one direction in an adjustable manner.

3. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a vertically-arranged support, a sleeve slidably connected to the support, a connection between the sleeve and each disk gang, and a screw for holding the sleeve against movement in one direction in an adjustable manner.

4. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a vertically-arranged support, a sleeve slidably connected to the support, a cross-bar pivotally supported by the sleeve, a connection between the cross-bar and each of the disk gangs, and means for holding the sleeve against movement in one direction.

5. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a vertically-arranged support, a sleeve slidably connected to the support, a cross-bar pivotally supported by the sleeve, a link connecting each disk gang with the cross-bar, and means for holding the sleeve against movement in one direction.

6. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a seatsupport, a sleeve slidably connected to the seat support, a connection between the sleeve and each of the disk gangs, and means for holding the sleeve against movement in one direction.

7. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, a seatsupport, a sleeve slidably connected to the seat-support, a cross-bar pivotally supported by the sleeve, a connection between the crossbar and each of the disk gangs, a bracket fiX- edly connected to the seat-support and located above the sleeve, and a screw supported by the bracket having its lower end engagin the sleeve.

8. In a disk harrow, the combination of a tongue, a frame secured to the tongue, two disk gangs connected to the frame, the connection comprising a brace-b ar provided with a notch in one edge, a slide adj ustably connected to the brace-bar and provided with a hook, and a support connected with a disk gang adapted to be secured within the notch of the brace-bar by the slide.
